track and hold gen.zip - 3 KB

Inspired by this post of a new module by Mystic Circuits. I wanted to see if I could recreate the “track and hold“ function in the module inside [gen~]. Figure it’s been a while since I posted any Max stuff too.

gen~のFM音源負荷 #maxmsp #gen

先日のオシレーター負荷一覧とは関係ないですがFM作ってるのでどうするのが軽いかテスト。2opでキャリア側にフィードバック付き

------------------------------------------------------------------------------------

その1. mspオブジェクトのpeekでbufferにサイン波を書き込みgenのwaveで読んだものを10個複製

wave(buff, phasor(freq) + wave(buff, phasor(freq) ) * mod + cx * fb);

buffがバッファ変数、modがモジュレーション深度(0.7)、cxはフィードバック用のhistoryでfbがフィードバックレート(0.5)

------------------------------------------------------------------------------------

その2. genオブジェクト完結、sin()関数を2つ使用。同じく10個複製

sin(TWOPI * phasor(freq) + sin(TWOPI * phasor(freq)) * TWOPI * mod + cx * fb * TWOPI);

TWOPIだらけですが定数なのでたぶん大丈夫。 フィードバック量などは上と一緒。

------------------------------------------------------------------------------------

という感じで 音質は聞いた感じはほぼ変わらないんですがwave()の方はモジュレーションしていないサイン波の時点で余計な倍音が結構出ているので4opぐらいでちゃんと作ったら影響出て来てしまうかもしれない感じでした。（3opで変な感じになったのこれかも）

（上がwave()、下がsin()。peekとかつかうとさらに山が追加されます）

とにかくたいしてCPU負荷減らないっぽいのが残念でした。ポインタ参照とかに出来てないとかそういう理由なんでしょうか。そろそろexternal作ろうかと思います...

------------------------------------------------------------------------------------

ついで

cycle(freq + cycle(freq) * freq * TWOPI * mod + cx * fb * 100 );

cycleオブジェクトだけでやる時のfeedbackがなかなか意味わからないので全然いい具合にならないんですが割とこういう状態のFMサンプルパッチ見かけてる。

Cycling '74 Expo Day 2

Day two started with a bang (puntastic): we were introduced to the brand new Gen~ object and all of its wonders. Most of which escaped me with my current level of maxspertise. Even so, the rooms atmosphere definitely emanated excitement, which I was able to physically feel. There's science!

The education panel then kicked off with some interesting personal stories about how one goes about teaching Max/MSP to students. An amusing consensus was to start with generated music that featured some form of the string: Toggle > Metro > Random > Notein > Noteout. Much laughter. However, behind the narrative joy were some real positive messages including the diversity of Max for the teaching of many different kinds of students from those in media, games, even as far as architects. Being a Maxspert is now a cool thing!

The later presentations began with a performance from the creators of Monome: Brian Crabtree and Kelli Cain. Their perfect touch of almost sibling banter and serious passion for their product really made the presentation invite much attention. Check out Monome.org for more info.
